  5. Pelagic Zone
  1. a The area of the pelagic zone above the continental shelves. Has abundant sunlight, moderate temperatures, and relatively low water pressure.
  2. b The shallow benthic zone that most organisms live in; located on the continental shelves and is populated by organisms such as sea stars, brittle stars, and sea lilies.
  3. c Has no sunlight because it begins at a depth of 4,000 meters and extends to a depth of 6,000 meters.

  4. The ratio of the mass of a substance to the volume of the substance; commonly expressed as grams per cubic centimeter for solids and liquids and as grams per liter for gases.
  5. A popular method for desalinating ocean water. It includes the use of special membranes that allow water under high pressure to pass through and that block the dissolved salts.

  2. NektonAll organisms that swim actively in open water, independent of currents

          

  3. FreezingThe movement of deep, cold, and nutrient-rich water to the surface.

          

  4. PhytoplanktonMicroscopic plants in the ocean that provide food to many of the ocean's organisms.

          

  5. DesalinationA method of desalination where ocean water is heated to remove salt. Heat causes liquid water to evaporate and leave dissolved salts behind. When the water vapor condenses, the result is pure fresh water.
